Keratin - Strengthens Nails, Cartilage and More

Keratin is a family of proteins that are among the most important and versatile compounds ever produced in nature. Think of your hair, nails and skin as solid structures – like buildings, armour and carbon fibre – they’re all built for toughness and protection using keratin as the main component. However, in the human body, unlike the industrial world of mechanics and machines, keratin can also help injured cells to heal and grow.

Keratin is an extremely strong protein that is a major component in skin, hair, nails, joints and teeth. The amino acids which combine to form it have several unique properties and, depending on the levels of the various amino acids, it can be inflexible and hard, or soft, as is the case with skin.

Keratins deliver an exceptionally high content of the amino acid cysteine, which is in itself an abundant source of sulphur molecules that nourish and strengthen cartilage tissues, plus form the necessary layers make our nails strong and bright.

Supplementing our body with keratin also helps us to have smoother skin and fuller hair. Indeed clinical studies have shown decreases in hair loss and improvements in hair strength and ‘brightness’ with keratin supplementation over a 3-month period.
